Bucho turns out to be the brother of El Mariachi. He and Carolina head over to Bucho's villa and give themselves up, seemingly unarmed. After a brief exchange, El Mariachi pulls out a pair of handguns that he's hidden in his sleeves and shoots a number of furious rounds directly into the camera. The scene fades out, and we're left to conclude that he was successful in his objectives.After visiting the little boy in the hosptial, El Mariachi leaves town carrying his guitar case full of guns. Carolina catches up to him in her jeep("I want you to thank me right now") and the two of them drive off together with Tito and Tarantula's "Back to the House that Love Built" playing in the background.

When the bad guys try and kill Antonio Banderas in the bookstore, after killing about the third bad guy, you can clearly see his gun lock on an empty chamber, but there's a cut and he immediately carries on shooting.
